| + | ==Mathematical Symbols== |
| + | |
| + | This page is a quick reference for the "standard" mathematical symbols in [[HTML]] that should work on most browsers, and is intended mainly for people editing mathematical articles on Wikipedia. |
| + | |
| + | *'''Numbers:''' {{unicode|¼ ½ ¾ ¹ ² ³}} ¼ ½ ¾ ¹ ² ³ |
| + | *'''Analysis:''' {{unicode|∂ ∫ ∑ ∏ √ ∞ ∇ ℘ ℑ ℜ}} ∂ ∫ ∑ ∏ √ ∞ ∇ ℘ ℑ ℜ |
| + | *'''Arrows:''' {{unicode|← ↓ → ↑ ↔ ↵ ⇐ ⇓ ⇒ ⇑ ⇔}} ← ↓ → ↑ ↔ ↵ ⇐ ⇓ ⇒ ⇑ ⇔ |
| + | *'''Logic:''' {{unicode|¬ ∧ ∨ ∃ ∀}} ¬ ∧ ∨ ∃ ∀ |
| + | *'''Sets:''' {{unicode|∈ ∉ ∋ ∅ ⊆ ⊇ ⊃ ⊂ ⊄ ∪ ∩ ℵ}} ∈ ∉ ∋ ∅ ⊆ ⊇ ⊃ ⊂ ⊄ ∪ ∩ ℵ |
| + | *'''Relations:''' {{unicode|≠ ≤ ≥ < > ≡ ≅ ≈ ∝}} &ne; &le; &ge; &lt; &gt; &equiv; &cong; &asymp; &prop; |
| + | *'''Binary operations:''' {{unicode|± − × ÷ ⁄ ⊥ ⊕ ⊗ ∗}} &plusmn; &minus; &times; &divide; &frasl; &perp; &oplus; &otimes; &lowast; |
| + | *'''Delimiters:''' {{unicode|⌈ ⌉ ⌊ ⌋ ⟨ ⟩ « »}} &lceil; &rceil; &lfloor;&rfloor; &lang; &rang; &laquo; &raquo; |
| + | *'''Miscellaneous:''' {{unicode|† ¦ ∠ ∴ ◊ • ♠ ♣ ♥ ♦}} &dagger; &brvbar; &ang; &there4; &loz; &bull; &spades; &clubs; &hearts; &diams; |
| + | *'''Punctuation:''' {{unicode|′ ″ ‾ ˆ ° ⋅ · … – —}} &prime; &Prime; &oline; &circ; &deg; &sdot; &middot; &hellip; &ndash; &mdash; |
| + | *'''Spacing:''' thin ( ), n-width ( ), m-width ( ), and non-breaking spaces ( ). &thinsp; &ensp; &emsp; &nbsp; |
| + | *'''Greek:''' α β γ Α Β Γ etc. &alpha; &beta; &gamma; &Alpha; &Beta; &Gamma; etc. |
| + | *'''Unicode:''' &#x22A2; (for example) gives the character ⊢ with [[unicode]] number x22A2 (hexadecimal). Warning: many of the more obscure unicode characters do not yet work on all browsers. |
| + | |
| + | It might be easier to just copy and paste the symbols instead of using them by reference. |
